Arguments:

Name	Type	Description
hMark	HIG_ARTX_TEXT_FROM_FILE	Annotation handle.

The value of the text string is the path to a file. The annotation is drawn using the contents of this file.
If lpszTextBuffer is NULL, then the number of bytes required to copy the annotation text string is written to pnDataSize.
If lpszTextBuffer is not NULL, then the actual number of bytes copied to lpszTextBuffer is written to pnDataSize.
